Create isolated foundation types and parameters

00:04

An isolated foundation's incidence parameters can

00:06

carry information relating to host level,

00:09

higher offset from level reinforcement covers.

00:12

And if the foundation will move with a grid,

00:14

it also contains read only parameters relating to

00:17

the top and bottom elevations of the foundation.

00:21

In the image shown below, the isolated foundation family has a parameter named cap.

00:26

If this is enabled,

00:27

then the elevation at the bottom is shown at

00:29

the underside of the cap indicated by the red line

00:32

in each isolated foundation family.

00:35

A parameter named material for model behavior

00:37

controls how elements join to other elements.

00:40

And if they can host reinforcement bar,

00:42

the image on the left shows two isolated pad foundations

00:46

with the material for model behavior set to concrete.

00:49

This enables the foundations to merge and gives the

00:52

correct quantities of concrete and an accurate drawing output.

00:55

The image on the right shows some sheet pining

00:58

these elements do not want to join.

00:60

So the material for model behavior has been set to steal.

01:03

Other examples could be precast grade beams.

01:06

These would also not want to join to other concrete elements.

01:10

Generally,

01:11

the physical dimensions of the isolated

01:13

foundations are controlled with type parameters.

01:16

You can create new family types and assign type marks to each type of family.

01:21

The image below shows various parameters for controlling the

01:24

shape and size of a triangular pile cap.

01:27

We'll begin by opening up the structural plan top of foundation.

01:33

Let's zoom up on grid B three.

01:35

And here we can see that we have a pile cap with four piles nested in.

01:39

Let's first review the instance and type

01:42

parameters for this particular isolated foundation family.

01:46

So go ahead and select the family

01:48

and in the properties pallett,

01:49

you'll note here that we have a number of instance parameters.

01:53

So we have a level that the foundation is hosted to.

01:56

Of course, we can change that at any time we like,

01:59

we then have a host.

01:60

So you can see in this case that it's the same level top of foundation,

02:04

we can offset the foundation above or below its current level.

02:08

And you'll notice at the moment that this will move with grids

02:13

under dimensions here,

02:14

you'll notice that we have elevation at top and elevation at bottom.

02:18

So the elevation at top is the level at the top of the pile cap.

02:22

Elevation at bottom is currently showing us the level at the bottom

02:27

of the pile rather than at the bottom of the cap.

02:30

So we'll edit this a bit later on.

02:32

Let's now take a look at the type parameters

02:35

in the property's pad. Go ahead and select edit type

02:40

in the type properties dialogue box.

02:42

You'll note here that we can see our dimensions for the pile cap.

02:45

So here we can see the length, the width,

02:47

the cut off the clearance and also the foundation thickness.

02:52

The physical pile itself is set here under construction.

02:56

If I go to the pull down menu here, you can see presently, I have three types of pile,

03:05

Of course,

03:05

these piles are nested into the pile cap and we can select

03:08

this family that we want to use within our pile cap.

03:11

Ok? So now that we've reviewed the type properties, let's go ahead and select, ok?

03:16

And we're now going to create our own pile cap and pile.

03:20

Let's first begin by creating a new pile.

03:23

So in this example, we require a pile that's 36 inch diameter

03:28

to do this. In the project browser will expand the family's folder

03:33

and in the family's folder, we'll go ahead and expand structural foundations

03:38

under structural foundations, would also expand pile steel pipe

03:43

and notes here that we have those three different types available.

03:48

Let's begin by selecting a 24 inch diameter type.

03:51

We'll right mouse click and we'll select duplicate.

03:55

We can now go ahead and name this family type. So this one's going to be 36 inch

04:00

and we'll just remove the two at the end.

04:03

And now we right mouse click over this and go to type properties

04:08

in the type properties dialog box,

04:10

you'll now notice that we have a 36 inch diameter pile.

04:13

And of course, here we can now set through various different dimensions.

04:17

So the diameter will now be 3 ft,

04:20

the depth of the pile will set to 25 ft

04:23

and we'll leave the embedment at six inch.

04:27

If we look under the identity data here, we can see that we have an assembly code

04:31

and we have an assembly description and the omni class number and omni class title.

04:37

This is already set for us.

04:38

So we can go ahead and select, OK to the type properties dialog box

04:43

to create our new pile cap and pile.

04:45

We'll first begin by selecting this pile cap here,

04:49

right mouse click. And here we'll select create similar.

04:53

We'll go ahead and place one of these pile

04:55

caps and piles just here on this grid intersection

04:59

on the context ribbon. I'll go ahead and select modifier.

05:03

We can then select our pile cap

05:06

and in the type properties dialog box, we'll select edit type.

05:11

So I'm going to begin by duplicating this pile cap type.

05:15

And of course, here we can give this a new name. So this will be 60 inch

05:20

by 60 inch

05:21

by 35 inch deep and click, ok.

05:26

In the pile type dropdown menu here,

05:29

we can now see our 36 inch diameter pile that we've just created.

05:33

So we'll select this to get this nested in

05:36

and then here we can simply just now set our width. So that will be 60 inches

05:41

and 60 inches for the length,

05:44

the foundation thickness will remain at 2 ft and 11 inches.

05:47

And of course, here again,

05:49

you can see that our assembly code and assembly description and

05:52

omni class number and title are all set for us.

05:56

We can simply now click, ok.

05:58

And you can now see we have our new family type created.

06:02

Now, of course, if we take a look into the property's paddocks,

06:05

we can see we have an elevation at top and an elevation at bottom.

06:10

The elevation at bottom parameter is currently showing us the bottom of the pile.

06:14

In this case, it's negative 28 ft and 11 inches.

06:18

Let's go ahead and change this

06:20

on the context ribbon. We'll select edits family

06:26

in the family, editor in the properties pad. It, you'll note here that we can set cap.

06:31

If I set cap, I can now load this into the project and close.

06:37

In this example, I will not save changes to the pale

06:40

family.

06:42

And here we'll overwrite the existing version.

06:46

If I now go ahead and select our pile and pile cap,

06:49

you'll now notice here that we have an elevation at top of negative 1 ft

06:54

and an elevation at bottom, which is of course the underside of the pile cap

06:59

to complete the model,

06:60

we'll place down another three piles with the pile cap still

07:03

selected we'll right mouse click and select to create similar.

07:08

And we'll now place a pile cap here

07:11

here

07:12

and here

07:15

to release the command, we'll select, modify on the context ribbon.

07:19

And finally, if we switch the view to the 3D foundation,

07:23

we can now inspect our new family type.

07:26

So to summarize, we've been able to inspect the instance parameters,

07:30

set some type parameters.

07:32

We created a new pile type and then we used that within a new pile cap family.
